Keira Knightley has revealed that she was originally worried about becoming the face of Chanel’s Coco Mademoiselle fragrance. The British actress admitted that she wasn’t sure how well the adverts would be received to begin with. She told Stylist magazine, “With the first one I think we were all a bit worried because we didn’t know if it was going to sell well and it was taking over this enormous thing. “It was quite frightening. But the latest one, because we went with the same team we had a really lovely time.” The 25-year-old added, “It’s always nice to have an occasion to wear a silly frock and get dolled up.”
